Foveal neovascularization in diabetic retinopathy

Retinal neovascularization in diabetes mellitus almost always occurs at the optic disc and/or near the major nasal and temporal vascular arcades, sparing the foveal area. We examined seven eyes of seven patients with long-standing insulin-dependent diabetes mellitus who had unilateral foveal retinal neovascularization. The neovascularization originated from the perifoveal capillaries and demonstrated typical leakage on fluorescein angiography.
